Not sure about the RPM or Wheel thing.... It is a lower pitch and there is no pulsing or vibration. Car seems to drive fine and it keeps accelerating. It just sounds like the engine starts making an unusual noise once I hit the 90-100 mark and have my foot on the floor. Thanks for the comments

I'm kinda thinking wheel bearings right now...:dunno:
But if I have to blindly guess at this point...are the secondaries opening on time?
